Shaun if you have an external HDD to hand then just copy the etka file from the c: drive to the external hdd, then you can drag it from the external onto another pc/laptop this will keep all the updates you've done. This took me a couple of days to update all VW, Audi, SEAT and Skoda but worth it in the end just to compare prices through the vag range. Also if you go into the etka file and open the prog folder in there you will find 4 files ETKA_AU, ETKA_VW, ETKA_SK and ETKA_SE you need to page down to where you will see this:
[KONZERN]
firmen=VW,AU,SE,SK
defaultmarkt=RDW
firma=AU
The Firmen line will just have a single name in it you need it to look like the above, once you've done that Skoda and SEAT will be on the front page
